SANTA CLARA -- The 49ers began their offseason program Monday, and Colin Kaepernick was in attendance. It's the first step toward possibly restarting the quarterback's career under new coach Chip Kelly.
Whether Kaepernick maintains that course or pursues a trade at a cheaper salary elsewhere is up to him, a team official said on the condition of anonymity.
A source told this news organization three weeks ago that Kaepernick wouldn't boycott the 49ers program, and that held true despite trade talks having heated up last week when Kaepernick met twice with Denver Broncos general manager John Elway.
That potential trade is at a standstill, however, because of financial issues, and no other team has emerged as a serious suitor, the team official said.
Kaepernick's $11.9 million base salary became guaranteed when he remained on the 49ers roster through Thursday. He stands to earn a $400,000 bonus for participating in 90 percent of the offseason program.
Neither Kaepernick nor Kelly was available for comment Monday, as no media access was granted. Kaepernick flew to the Bay Area on Sunday night from Colorado, where he has been rehabilitating from surgeries on his left shoulder, left knee and right thumb.
Kaepernick, 28, is entering his sixth season. He made 47 consecutive regular-season starts before then-coach Jim Tomsula benched him after eight games in favor of Blaine Gabbert, who went 3-5 as the 49ers closed a 5-11 2015 season. The 49ers are hoping that Kaepernick will embrace Kelly's up-tempo offense and compete with Gabbert for the starting job.
Gabbert is entering the final year of his contract, at a $1.75 million base salary. The 49ers' other quarterbacks under contract are Dylan Thompson, undrafted a year ago out of South Carolina, and Thad Lewis, a journeyman who was the Philadelphia Eagles' No. 3 quarterback last season under Kelly.
The 49ers could add another quarterback in the draft, where they hold the seventh overall pick April 28.
Although Kelly is allowed to talk football for the first time with his players and issue them iPad playbooks, he and other coaches aren't allowed to interact or watch them on the field these next two weeks.
The first phase of the offseason program is limited to strength and conditioning, or rehabilitation, as will be the case with Kaepernick.
