Seattle Seahawks first-round right tackle James Carpenter suffered an injury during practice and will undergo an MRI on Wednesday night, Danny O'Neil of The Seattle Times reports.
Dave Boling of the Tacoma News Tribune says it was a knee injury, which the Seahawks have confirmed.
Selected with the 25th overall pick of the 2011 NFL Draft, the former Alabama left tackle was immediately penciled in as the right tackle bookend to 2010 first-round pick Russell Okung. Carpenter started the season-opener at left guard before moving back to right guard and is the only Seahawks' offensive player to not miss a snap this season.
Seahawks third-round right guard John Moffitt was placed on injured reserve this week with a PCL and MCL to his right knee, which he injured in the first quarter of Sunday's 22-17 win over the Baltimore Ravens. Veteran Paul McQuistan will replace Moffitt in the starting lineup.
