Chicago ? The Chicago Cubs aren’t taking any chances with Kerry Wood.

Wood went on the disabled list Thursday after the Cubs decided they didn’t want the right-hander returning to the rotation until his sore triceps was completely healed. Wood threw 24 pitches in a bullpen session Thursday morning to see if he was ready to come back, possibly as early as Sunday.

“Woody’s session went extremely well and he feels about 95 percent,” general manager Jim Hendry said. “I don’t want him going out there Sunday at even 95 percent. We’re going to take the conservative route.

“He really could pitch Sunday,” Hendry added. “I don’t have any doubts about that. But 95 percent on May 20, that’s not good enough. It’s going to be 100 percent.”

The move was backdated to May 12, the day after Wood left a game after two innings because of tightness in his right triceps. A five-game suspension that Wood had completed Wednesday night for confronting plate umpire Eric Cooper on April 17 about balls and strikes was reinstated.

“I think what will happen is the suspension will be reinstated, as will the appeal,” said Sandy Alderson, executive vice president of baseball operations.

Wood, 3-3 with a 2.82 ERA and 52 strikeouts, will be eligible to come off the disabled list next Thursday, an off day for the Cubs.

Tests on Wood last week showed inflammation in his triceps, but no tears. He rested for a few days before starting to throw again Monday. In his bullpen session Thursday, he threw fastballs, sliders and curveballs during his bullpen session, working out of the windup and out of the stretch.
