Jays' Ryan told to quit throwing for week

Romero plays catch; Marcum to toss in 'pen Thursday

KANSAS CITY -- Blue Jays pitching coach Brad Arnsberg said Wednesday that reliever B.J. Ryan will be on a no-throw schedule over the next week after undergoing an MRI in Dallas.

Ryan has been on the disabled list with left trapezius tightness after appearing in six games this season.

"[The MRI] came back really clean," Arnsberg said. "No really eye-opening things. There was a little bit of inflammation up in the trap. That could even be from the deep friction massages he has been getting. They are going to give him seven days [from Wednesday] of no-throw. He'll be there two or three days and then meet us back in Toronto. They just want to let it tame itself down and then we'll go back to the drawing board."

In other pitching injury updates, Arnsberg said left-hander Ricky Romero (strained right oblique) played catch on Wednesday and felt fine.

"We'll back him up 60-75-90 feet on Thursday," Arnsberg said. "Eventually, he'll go back to 120 feet and then go to bullpen work from there. He's probably a week away from really being able to throw with a little bit of vengeance with the arm coming downhill. He'll do it in increments." Right-hander Shaun Marcum, recovering from Tommy John elbow ligament transplant surgery, is scheduled to throw a fastball/changeup bullpen session on Thursday. "We won't spin the ball off the mound at all," Arnsberg said. "That will be down the road a little bit. He'll go 35 pitches."
