Both players have had less-than-stellar seasons after doing quite well last year. Kelly, 26, has a 4.37 ERA (3.93 FIP) in seven starts this year. Since coming off the disabled list in mid-July, Kelly has a 7.32 ERA in four starts.
Craig, who turned 30 on July 18 and has struggled to stay healthy, has posted a weak .237/.291/.346 line in 2014.
Craig is signed through the next three seasons - 2015: $5.5M, 2016: $9M, 2017: $11M - with a $13M club option for 2018. Kelly is arbitration eligible after 2015.
So what does the rotation look like now?
Clay BuchholzAnthony Ranaudo - 1.94 ERA in last 10 AAA starts - is scheduled to start on Friday, but whether that is for Pawtucket or Boston (in his major league debut) is unclear.
