UPDATE (12:50pm on Monday) -- Jim Harbaugh took to Twitter to clarify his remarks on Colin Kaepernick:
SANTA CLARA – Bruce Ellington’s hamstring injury has placed his availability for the start of the regular season in doubt.
SANTA CLARA – Colin Kaepernick is still supposedly competing to be the 49ers’ starting quarterback for the opening of the regular season.
SANTA CLARA – The 49ers on Sunday released veteran offensive lineman Erik Pears, leaving the team with no obvious choice to serve as the swing tackle during the regular season.
Colin Kaepernick spoke up for himself again Sunday, and the number of minds changed by his fuller explanation of why he is no longer going to stand for the National Anthem is not yet known.
