CLEVELAND (AP) -Browns quarterback Charlie Frye may have broken his right wrist during Sunday's win over the Kansas City Chiefs.

Frye got hurt on Cleveland's first offensive series when he braced himself while being knocked down. He stayed in and threw a 23-yard touchdown pass to wide receiver Braylon Edwards before being taken to the locker room for X-rays.

Frye returned with 5:53 left before halftime, and drove the Browns to a tying score with 19 seconds left.

However, when Cleveland came out for the second half, Frye was wearing a large brace on his wrist and an orange jacket but no shoulder pads.

``I tried to fight it off for a while,'' said Frye, who also hurt his left ankle on the same play. ``At halftime, the trainer pulled the plug on it. I should know tomorrow just how serious it is.''

Tight end Kellen Winslow blurted out that Frye's wrist was broken, but later backtracked on his claim.

Backup Derek Anderson, who had only taken one previous snap in his two-year NFL career, took over for Frye and threw two TD passes in the final nine minutes of regulation to rally the Browns to a 31-28 overtime win. Anderson was Cleveland's third-string QB last season, behind Frye and Trent Dilfer.

Coming off a four-interception performance against Cincinnati, Frye went 11-for-13 for 122 yards. In his first full season as a starter, Frye has taken a beating behind an injury-depleted offensive line, but has not missed any significant time.

That will change if his wrist is broken, and even if it's not, Frye will not likely be ready to play Thursday night when the Browns (4-8) visit the Pittsburgh Steelers.

Browns coach Romeo Crennel said Frye will be evaluated Monday at the Cleveland Clinic and the club will have more information on his injury after more tests are completed.

Frye was still wearing the brace when he left Browns Stadium after the game.
