Velasquez (elbow) is expected to throw a bullpen session Thursday, Ryan Lawrence of PhillyVoice.com reports.
The right-hander continues to recover from a strained elbow, which landed him on the DL at the end of May. If Thursday's session goes well, a clearer timetable could be available, but at this point the team has not indicated when it expects Velasquez to return to the mound.
