Adrian Beltre left Tuesday's game in Boston with tightness in his left quadriceps muscle. Manager Ron Washington told reporters after the game that Beltre would be sent back to Texas to have the leg examined.
The Rangers' regular third baseman, who turned 35 on Monday, started the game at designated hitter against Felix Doubront and the Red Sox.
Texas was leading 9-1 when Jim Adduci was called on to pinch-hit for Beltre in the top of the sixth. Beltre typically plays through minor leg injuries. With a big lead, the move could very well have been precautionary. The early return to Texas, however, is much more of a red flag than originally anticipated.
Josh Wilson replaced Beltre at third base in the sixth inning Tuesday, and is the probable replacement Wednesday. A roster move would likely be made should Beltre be unavailable for an extended period of time.
Beltre missed a week of action in spring training with a similar injury, and has battled leg injuries for much of his tenure as a Ranger.
The Rangers play a 3:05 game at Fenway Park on Wednesday and have a travel day Thursday, so Beltre's earliest return to the lineup will be Friday against Houston.
Beltre went 2-for-3 with two RBI through the first five innnigs Tuesday, pushing his season average to .286. He missed just one game in 2013.
