CLEVELAND -- The Browns are keeping Jake Delhomme's injured right ankle under wraps.
The team did not provide a medical update on Delhomme, who underwent an MRI on Tuesday after injuring his right ankle while throwing a game-swinging interception late in the first half of Sunday's season-opening loss at Tampa Bay. It was the veteran's debut with the Browns.
Delhomme played the entire second half on an ankle coach Eric Mangini described as being "twisted up" by his quarterback. A team spokesman said the Browns "will not have anything on Jake," and declined to offer any other information.
The Browns host Kansas City on Sunday in their home opener. If Delhomme can't play, backup Seneca Wallace could start against the Chiefs (1-0).
Mangini is expected to provide an update on Delhomme before practice Wednesday. Delhomme, who threw two picks in Cleveland's 17-14 loss, is also scheduled to speak with reporters as the Browns begin installing their game plan for the Chiefs.
Cleveland signed Delhomme as a free agent in March, days after trading for Wallace and releasing former starter Derek Anderson. Wallace spent the previous seven seasons in Seattle with Browns president Mike Holmgren, who coached the Seahawks.
Wallace, who is 5-9 in 14 career NFL starts, also made his debut for the Browns on Sunday, but not at quarterback. He lined up for four plays at wide receiver and caught one pass for 9 yards from Joshua Cribbs when the Browns went to their "Cyclone" package.
