The Rays also activated outfielder Brandon Guyer, who had been sidelined by a broken left thumb, from the 15-day DL in moves made before Thursday night's game against Houston.
DeJesus was hurt on a check-swing in Wednesday's game against Baltimore. One day earlier, he ran hard into the left-field wall chasing a grand slam hit by Orioles' slugger Chris Davis.
DeJesus says ''you can go run full steam into a wall and not be hurt, and then something I do every day you take for granted sometimes (you get hurt).''
DeJesus expects to be in a cast for three weeks. He will undergo additional tests to determine how long he will be out.
