REGINA, Saskatchewan (AP) -Running back Ricky Williams broke his left arm in the second quarter of the Toronto Argonauts' 26-23 victory over the Saskatchewan Roughriders on Saturday night and is out indefinitely.

Argonauts coach Mike ``Pinball'' Clemons confirmed the injury but did not specify which bone was broken.

``He has a broken arm, so he's going to be out for a little while,'' Clemons said.

Williams, who was not available for interviews, left the game midway through the second quarter after a 3-yard gain when he was tackled by several Saskatchewan players, including linebacker Mike McCullough. X-rays taken at a Regina hospital revealed a broken bone.

``He was actually holding himself off the ground,'' Clemons said of Williams. ``He was running with the ball and he was trying to hold himself up, I think. It was a pile of people and we saw him coming down.

``We knew he was hurt when he came off the field. It looked like it was his shoulder (from) the way he was leaning, but it turned out be his arm.

``You're talking about some fortitude. It's a clean break. He just came off quiet, didn't say a thing. Like, I'd have been screaming.''

Williams finished with 17 yards on four carries, including one run of 16 yards. He entered Saturday's game sixth in the league in rushing with 214 yards on 53 carries with one touchdown in four games.

Williams is playing in the CFL after he was suspended by the NFL for one year after a fourth positive drug test. He is still under contract with the NFL's Miami Dolphins.

Any games Williams misses will be the first he sits out due to injury since a broken left ankle forced him to miss the last six games of the 2000 NFL season, when he was with the New Orleans Saints.
