Bassitt (face) isn't listed as the probable starter for Thursday's game against the Mariners, Matt Kawahara of the San Francisco Chronicle reports.
Thursday's series finale was previously mentioned as a possible return date for the 32-year-old but James Kaprielian will instead receive the starting nod. According to Shayna Rubin of The San Jose Mercury News, Bassitt felt good after throwing about 30 pitches during a bullpen session Monday, which should still give him an opportunity to return later in the week.
