Houston defensive end Isaiah Chambers, the team leader in sacks, announced on social media that he has an injury that will end his season.
He suffered a knee injury in the Cougars' 41-26 victory over Tulsa on Oct. 4.
Chambers posted a message on Instagram, which reads: "My season sadly came to end due to Injury last week , @NFL I'm still coming for you Made a Promise to my mom I must fulfill , People go through way worse things then not playing football , I'm blessed .To Next year."
The Houston football program has not commented on Chambers' status or on the specifics of the injury.
Chambers, a redshirt sophomore, has recorded 4.5 sacks this season to lead the team and his six tackles for loss are second on the team to All-American Ed Oliver's 6.5.
Chambers transferred to Houston from TCU in August 2017.
As a true freshman in 2016, Chambers redshirted the season. He was expected to contribute at TCU last season before transferring.
Houston is 4-1, including 1-0 in the American Athletic Conference. The Cougars play road games against East Carolina and Navy in their next two contests before hosting No. 23 South Florida on Oct. 27.
