Injuries we're tracking from Sunday's Week 4 games

Here are the injuries we're monitoring on the fourth Sunday of the 2018 NFL season:

1. Seahawks safety Earl Thomas (leg) was carted off the field with an air cast against the Cardinals. Coach Pete Carroll told reporters after the game that he suffered a lower leg fracture and will go on injured reserve.

Seahawks rookie tight end Will Dissly left Sunday's game early with a knee injury against the Cardinals and did not return after he was carted off.

Following the game, NFL Network Insider Ian Rapoport reported that Dissly, who had quickly emerged as a favorite target for quarterback Russell Wilson, "is believed to have suffered a torn patella and is out for the season."

Dissly will finish his rookie season with eight catches for 151 yards with two TDs.

2. Bengals tight end Tyler Eifert was carted off the field with an air cast on. He'll have ankle surgery and his season is likely over.

3. Colts receiver T.Y. Hilton (hamstring) was injured, returned and then was ruled out late in the second half versus the Texans. In the postgame press conference, Indy coach Frank Reich said Hilton's status for Thursday night's game versus the Patriots was "probably not good."
