Matt Milano suffered an apparent knee injury and had to be carted off the field Sunday in London against the Jacksonville Jaguars.

The Buffalo Bills linebacker was having a strong start to the season, but the initial look at the injury does not look good. According to sideline reporter Jamie Erdahl, Milano had a full cast from his shin to his thigh, which is indicative of more than just a minor injury.

However, no official word has been given concerning Milano as of Sunday morning.

Milano is entering his 7th season in the NFL, all of which have come in Buffalo. So far this season he’s totaled a pair of interceptions with a forced fumble and 27 tackles.
