The Cubs are shutting down Matt Guerrier the reliever they had salvaged in the Carlos Marmol trade.

Guerrier was scheduled to fly back to Chicago on Thursday and have his right elbow examined by Dr. Stephen Gryzlo. The Cubs are calling it soreness for now but know it’s serious enough to put Guerrier on the 60-day disabled list.

Guerrier told manager Dale Sveum he felt something throwing a curveball to Chase Utley during Wednesday night’s 5-2 win over the Philadelphia Phillies. That seventh inning began with Thomas Neal collapsing in left field after dislocating his right shoulder on a throw. Then there was Utley running over catcher Dioner Navarro.

As Sveum said: “Luckily Navarro’s isn’t as major as we thought but it was possible (we had) three major injuries in a five-minute span. I don’t think I’ve ever seen that in a game before.”

The Cubs put Neal on the disabled list and promoted catcher J.C. Boscan from Triple-A Iowa while treating Navarro’s right ankle. Eduardo Sanchez up from Des Moines took Guerrier’s spot in the bullpen.
