Frank Francisco will likely miss the start of the regular season after being diagnosed with tightness in his right pectoral muscle and inflammation in his right biceps muscle.

Francisco received the news after visiting Dr. James Andrews in Birmingham, Ala. Dr. Andrews also confirmed an earlier report that there is no structural damage in the affected area, which potentially would have required surgery.

That bit of good news means the 31-year-old Francisco is set to resume his rehab at the beginning of next week.
