Stock report from Day 10 of 49ers training camp

Day 10 was the San Francisco 49ers’ most back-and-forth practice of training camp. The team portion of practice began with quarterback Jimmy Garoppolo showing off decisiveness in the red zone. It ended with a turnover during a two-minute drill. In between, the 49ers suffered a pair of injuries that cast a shadow over an otherwise eventful practice.

Here’s our stock report after Day 10 of the 49ers training camp:

Stock up: Red zone offense

The 49ers focused on the red zone for a portion of their team period of practice. It was a series dominated by the offense. Quarterback Jimmy Garoppolo threw four touchdowns in a row, bouncing back and forth between receiver Trent Taylor and tight end George Kittle, who each caught two. It was an impressive change of pace for an offense that struggled when it neared the endzone during the season, as well as earlier in training camp during a similar session.

Stock down: DL Nick Bosa

The 49ers’ second-overall pick was at the bottom of a pile of offensive and defensive lineman after a run play. Bosa was on the field, cradling his lower right leg/ankle while being attended to by medical staff. He was on the turf for a few minutes before getting up and walking to the training facility under his own power. Bosa also missed most of the offseason program with a hamstring strain. He’s currently undergoing an MRI to determine the severity.

Stock up: QB Nick Mullens

The 49ers’ tenth practice culminated with the two-minute drill in which the offense was tasked with moving the ball the length of field and scoring either a touchdown or field goal. Mullens and the second-string offense got the first go at it and didn’t disappoint. Mullens completed 4 of 5 passes on the drive, culminating with a touchdown pass. Four of his five throws were to the same target. More on that later. Mullens is the clear leader between him and CJ Beathard in the competition for primary backup to Garoppolo.

Stock down: CB Jason Verrett

In addition to Bosa, Verrett also left Wednesday’s practice with an ankle injury. He too is undergoing an MRI to determine the severity. The 49ers signed Verrett to a one-year deal during the offseason. The former Los Angeles Chargers cornerback is attempting a comeback after tearing his Achilles at the start of training camp last year. It was Verrett’s second second-ending injury in the last three years.

Stock up: TE Ross Dwelley

Dwelley was Mullens’ favorite target during the two-minute drill. The pair of second-stringers connected on three consecutive passes, quickly moving the 49ers offense down the field. After an incompletion intended for receiver Jalen Hurd, Mullens went back to Dwelley for the touchdown at the front of the endzone. Dwelley’s had a strong camp and showcases a knack for finding open space within the defense. He seems to have earned the backup role behind George Kittle.
