Indianapolis Colts defensive tackle Arthur Jones is set to undergo an MRI on Sunday after spraining his ankle in Saturday night's preseason win over the St. Louis Rams, NFL Network's Ian Rapoport reports.
Colts head coach Chuck Pagano said Jones was injured on the first play of the game. He was later spotted leaving the Edward Jones Dome with a walking boot on his lower left leg.
Jones missed six games in 2014 with a high ankle sprain and was limited for most of the season as a result.
"I just have to wait and see what the doctors say about how bad it is," Pagano said of the latest injury. "I have no idea right now how bad it is. Hopefully it's a quick turnaround and not a high ankle type of deal (that causes him) to miss the time that he missed last year."
