Gabbert has emerged as a clear favorite to win the starting quarterback job, according to Cam Inman of the Bay Area News Group.
Gabbert has reportedly been impressive in joint practices with the Texans, while Kaepernick has been limited by soreness in his throwing shoulder. It seems a bit early to make any assumptions, but Gabbert does look like the obvious choice to start Sunday's preseason game against Houston. To be clear, head coach Chip Kelly hasn't yet named a starter for the game.
