The cut on Michael Bourn’s right index finger has turned out to be more than a nuisance injury.

Manager Terry Francona said Tuesday that Bourn will go on the disabled list in a day or two, which means he cannot return to the lineup until at least April 30.

Bourn sustained the cut when Chicago White Sox reliever Matt Thornton stepped on Bourn’s hand as he was sliding into first base Sunday. It took five stitches to close the wound, but it was presumed that Bourn could return to the field after the stitches were removed, possibly in five to seven days.

ACTUAL MOVES — The Indians optioned catcher Omir Santos back to Triple-A Columbus and called up infielder Cord Phelps.

“Phelps deserves this,” Francona said. “He gives us another left-handed bat, a complementary bat. In spring training, he couldn’t have played much better.”

Phelps batted .375 with four doubles, one triple, three home runs, and seven RBI in 23 exhibition games. He played only two games at Triple-A because of a stiff neck.

Santos was no longer needed because Carlos Santana returned to the lineup after missing four games with a sore thumb.

Right-hander Robert Whitenack cleared waivers and was outrighted to the Double-A Aeros.

EXPRESSION OF SYMPATHY — A moment of silence preceded the first pitch and the center-field flag was at half-staff in honor of those who were injured or died in the Boston bombing incident.

Tribe president Mark Shapiro also expressed his sympathy on the part of the team and Major League Baseball. He also tried to reassure fans that the club stresses security for the fans.

“As always,” Shapiro said, “the Indians are committed to the safety of our fans. Of course, there is a heightened level of awareness today.”
