Robinson had four carries for 11 yards in Sunday's loss to Buffalo.

EDGE Analysis

Robinson is the clear backup to Frank Gore as the season begins. However, it doesn't look like he's going to have a significant role in the offense unless Gore gets hurt. Robinson played 21 snaps on offense with Gore playing 33 snaps - and that was with Gore missing some time with a leg cramp.

Robinson (concussion) is not listed on the Colts' Week 1 practice participation/injury report.

EDGE Analysis

With Boom Herron having landed on IR and Vick Ballard dealing with a hamstring issue, Robinson appears poised to open the season as Frank Gore's top backup in Sunday's season opener against the Bills.

Robinson (concussion) returned to practice Monday.

EDGE Analysis

With the release of Dan Herron and Zurlon Tipton, Robinson begins the season as the backup to Frank Gore. We'll need to see if Robinson holds up during a week of practice to gauge his availability for Week 1, but he could emerge with a significant role later this season if the 32-year old Gore gets hurt or wears down.

Robinson is still awaiting clearance to return from the concussion that he suffered in the Colts' third preseason game, the Indianapolis Star reports.

EDGE Analysis

Robinson's status takes on an added layer of importance, with Boom Herron having been waived/injured on Sunday. With Vick Ballard dealing with a hamstring issue, Frank Gore and Tyler Varga are the Colts' two healthy backs at the moment, but upon his return to the mix, Robinson is a candidate to move into the top backup spot vacated by Herron's injury.

Robinson (concussion) has made the Colts' 53-man roster and would enter Week 1 as the backup to Frank Gore with Dan Herron likely out with a shoulder injury, Indy Sports Central reports.

EDGE Analysis

Robinson could miss Week 1 as well as he'll need to prove he's healthy after suffering a concussion in the preseason. When Robinson does return, he'll enter the season as the No. 3 running back with the release of Zurlon Tipton. Robinson showed enough in the preseason it wouldn't be a surprise if he overtook Herron as the backup at some point.

Robinson (concussion) did not play in Thursday's preseason game, ESPN reports.

EDGE Analysis

It's not clear if Robinson will be ready for the start of the regular season. The Colts could be thin at running back behind Frank Gore with both Dan Herron and Vick Ballard suffering injuries in Thursday's preseason game. Robinson showed enough of a spark in the preseason that he could eventually be the No. 3 or No. 2 running back if healthy.

Robinson suffered a head injury in Saturday's preseason game and will go through the league's concussion protocol, the team's official web site reports. Robinson had five carries for four yards and one reception for four yards before departing.

EDGE Analysis

Robinson has had a strong training camp and was pushing for the third running back role, so hopefully this isn't a significant setback.
