The Baltimore Ravens have been without their backup quarterback, Robert Griffin III, for most of training camp. The team signed Joe Callahan after working out Josh Johnson. But it looks like his services won't be in need anymore since Griffin will be making his return soon.

According to ESPN's Jamison Hensley, head coach John Harbaugh says Griffin is on schedule for the regular season opener against the Miami Dolphins.

Griffin suffered a small thumb fracture to his throwing hand (right) early in training camp. The Ravens expected Griffin to be back by the regular season, barring setbacks. It appears as if he'll do just that, as the quarterback's recovery has been clear thus far. After his injury, Griffin joked around a bit on Twitter.

Harbaugh said in late July about Griffin's then-injury status:

“He won't be able to do anything until that fracture heals, which is a time frame,” Harbaugh said. “I think it was three-four weeks before it even heals and we'll work from there. We anticipate the first week of the season, if all goes well,” per NFL Media.

Griffin played the part of Lamar Jackson's mentor in 2018. The two, coming out of college, were comparable in many senses; dual-threat, Heisman Trophy-winning first-round picks. In 2019, he'll likely stay in the same role as his backup. If Jackson gets injured, the Ravens won't have to switch up their game plan.

In the meantime, another dual-threat is making waves as a Raven. Rookie Trace McSorley, hailing from Penn State, put on a show Thursday. He scorched the Philadelphia Eagles defense to the tune of 19-for-23 throwing for 203 yards and two touchdowns. He also added a running touchdown.
