Colts Injury Report: Anthony Castonzo, John Simon Remain Out

LOS ANGELES, CA - SEPTEMBER 10: Deyshawn Bond /

A couple of the Colts’ key players remained sidelined at Thursday’s practice ahead of Sunday’s trip to Houston to take on the division-rival Texans.

Andrew Luck being placed on season-ending injured reserve stole all the headlines on Thursday afternoon, but the Colts are struggling through injuries with some players on the active roster as well.

Left tackle Anthony Castonzo has not practiced yet this week with a knee injury. He is the most established player left on the Colts’ offensive line, and he was slated to match up with Jadeveon Clowney this weekend.

Jacoby Brissett has already been sacked more than any other quarterback in the league, and that number could rise if Castonzo is unable to play on Sunday.

John Simon is also out with a neck stinger, and he probably won’t travel to Houston to take on his former team this week.

Adam Vinatieri missed Wednesday’s practice with a sore back, but he returned as a full practice participant on Thursday. He should be good to go this week as he puts on an NFL uniform for the 360th time in his career.

Jabaal Sheard was able to practice fully on Thursday after he was limited at Wednesday’s practice. Sheard and Barkevious Mingo will be relied on to provide a pass rush with John Simon likely on the sidelines.

Cornerback Rashaan Melvin was also a full participant on Thursday as he continues to progress through the league’s concussion protocol.

Rookie Quincy Wilson has not practiced at all this week with a knee injury.
