Rodriguez (knee) is expected to rest a few days and then throw a bullpen session Friday, Mass Live reports.
Rodriguez acknowledged that he's still not feeling fully confident in the stability of the knee, which may have contributed to the reported loss of fastball velocity. Manager John Farrell said the Red Sox "fully expect" Rodriguez will pitch in the majors, but it's unknown how long it will take to get past the soreness or establish stability in the knee. As for his rehab clock, Rodriguez has 11 days left on that. If he's forced to sit out and rest for seven days or longer, they can restart the 30-day rehab clock. Rodriguez's condition allows Farrell to kick the decision about Clay Buchholz's spot in the rotation down the road a bit.
