Kaepernick returned to a complete practice Monday, throwing an array of short and deep passes. After the practice, he told reporters that his arm felt normal, per Matt Barrows of the Sacramento Bee.
It's a good sign that Kaepernick encountered no setbacks after throwing with improved velocity in Saturday's pregame session.
The arm fatigue sidelined Kaepernick for five practices as well as the first two preseason games, allowing Blaine Gabbert to gain a slight upperhand in the quarterback competition.
Although Gabbert has yet to give up a sack or toss an interception, he has missed throws and left plays on the field.
Kaepernick can make the quarterback decision a tough one for coach Chip Kelly if he clearly outplays Gabbert in Friday's regular-season dress rehearsal.
