INDIANAPOLIS – It’s looking like the Colts will have one key injury to watch this weekend.

That will be Marlon Mack (hamstring) who did practice all week with a hamstring injury that he has fought over a month and a half.

Along with Mack, here are some other tidbits learned from the Colts’ final day of practice prepping for the Texans:

  • The Colts are listing Marlon Mack as questionable for Sunday’s game, after the second-year running back practiced all three days this week. Mack was limited in each session. Probably the biggest indicator of Mack leaning towards not playing on Sunday is that the team promoted practice squad running back Jeremy McNichols to the 53-man roster on Friday afternoon. That gives the Colts 3 healthy running bakcs on the 53-man roster (Jordan Wilkins, Nyheim Hines and Jeremey McNichols), so there’s not an absolute need to have him dressed for Sunday.
  • Sunday will be the 38th different offensive line Andrew Luck has started behind in his career. It will be Le’Raven Clark’s third career start at left tackle, in place of Anthony Castonzo for a third straight week. At right tackle, Denzelle Good is likely to get the nod with Joe Haeg out due to a left ankle. Good has 19 career starts, all coming at right guard or right tackle.
  • Castonzo did practice on Thursday and Friday, as a limited participant both days. If Castonzo continues to progress, and practices early next week, perhaps he makes his 2018 debut against the Patriots. Remember, the Colts and Patriots play on Thursday night in Week Five.
  • With Jack Doyle not practicing at all the last two weeks (and still listed at ‘week-to-week’), the Colts will once again lean heavily on Eric Ebron for the tight end brunt work. These were the snap counts last week with Doyle out: Eric Ebron (52-of-59 snaps, 5 catches for 33 yards), Ryan Hewitt (16-of-59 snaps) and Erik Swoope (8-of-59 snaps, 1 catch for 7 yards). On Friday, the Colts waived Swoope and promoted Mo Alie-Cox from the practice squad.
  • The Colts will have a decision to make on Monday with Robert Turbin’s four-game suspension over. Turbin is a valuable veteran presence to a running back room filled with youth. Turbin has also been outstanding in short yardage during his two seasons with the Colts. Currently, the Colts have 4 running backs on their 53-man roster (Marlon Mack, Jordan Wilkins, Nyheim Hines and Jeremy McNichols). Those 4 guys are two rookies and two second-year players. For Turbin to come back onto the 53-man roster, the Colts will have to part ways with someone currently on the 53. Asked about Turbin on Friday, Reich had this to say: “He had a great offseason, a great camp. We really like Robert. As you know, there’s a lot of factors that go into that roster makeup and it can get complicated. It will be weighed heavily. We certainly appreciated the work that he did.”
  • Sunday will be Denico Autry’s first game action since the season opener. Autry is the team’s starting defensive tackle. Even though Margus Hunt has filled in nicely when asked to play in the interior for Autry, the Colts should stick with both of these guys in the starting lineup. That would have a 4-man starting defensive line of Jabaal Sheard and Margus Hunt at defensive end, and then Al Woods and Denico Autry at defensive tackle.
  • While the Colts already know 5 of their 7 inactives for Sunday, the Texans didn’t rule out anybody for Week Four. It will be a healthy Houston bunch arriving to Lucas Oil Stadium on Sunday afternoon.
  • In non-injury news, the Colts are honoring former linebacker Edwin Jackson at Sunday’s game. Jackson was killed by a drunken driver back in February. One of the most upbeat and positive guys in the locker room, Jackson was definitely a team favorite. On Sunday, the team will wear ‘EJ’ decals on their helmets, while the Colts will donate $25,000 to Jackson’s family for the Edwin Jackson 53 Foundation. Frank Reich never crossed paths with Jackson (Josh McDaniels backed out of the head coaching job two days after Jackson tragically passed away). Reich said the Colts had Jackson’s good friend Matthias Farley speak to the team this week about: “Matthias got up and talked about his passion and energy,” Reich said of Jackson. “I think the guys are appreciative to wear the decal to honor him.”



OUT: OT-Anthony Castonzo (hamstring), TE-Jack Doyle (hip), OT-Joe Haeg (left ankle, placed on injured reserve), DT-Hassan Ridgeway (calf), CB-Quincy Wilson (concussion)


             –Bowen’s Analysis: I’d expect Haeg and Wilson to miss Thursay’s game against the Patriots, as well.


QUESTIONABLE: S-Clayton Geathers (safety), RB-Marlon Mack (foot/hamstring), LB-Anthony Walker (groin)


            –Bowen’s Analysis: Geathers has missed at least 1 practice in each of the first three games, but has gone on to play each week. Walker was limited on Thursday and Friday.


The following players were on the injury report this week, but are good to go in Week Four: DL-Denico Autry (ankle), DE-Tarell Basham (personal), TE-Eric Ebron (shoulder/knee), S-Malik Hooker (hip/groin), QB-Andrew Luck (groin), DT-Al Woods (quadricep).
