Kelly (shoulder) will make another rehab start Monday at Triple-A Pawtucket, Alex Speier of the Boston Globe reports.

EDGE Analysis

With Eduardo Rodriguez also nearing a return from the disabled list, the Red Sox will have to make a decision between Kelly, Rodriguez, and Steven Wright for the No. 5 starter spot. Wright has more than held his own thus far while filling in, but his performance in his next scheduled start Wednesday in Kansas City may go a long way toward guiding the team's decision.
