Penn State continued its successful recruiting run since winning the Big Ten championship, receiving an oral commitment from a second consensus four-star player.

Cornerback Donovan Johnson, of Cass Technical High School in Detroit, announced his commitment Tuesday night on Twitter. The 5-foot-10, 175-pound Johnson, who was clocked at 4.35 seconds in the 40-yard dash last summer at a Nike camp, made an official visit last weekend to Penn State.

"I'm blessed to announce that I will be furthering my academic and athletic career at Penn State University," Johnson, the Lions' 17th pledge for the Class of 2017 and second cornerback, wrote on Twitter.

Last weekend, the Lions received a commitment from 5-9, 155-pound wide receiver K.J. Hamler of IMG Academy in Bradenton, Fla. Hamler previously attended Orchard Lake St. Mary's (Mich.), the same high school as former Penn State star wideout Allen Robinson.

Johnson and Hamler received four-star ratings from three leading recruiting web sites: Scout, Rivals and 247Sports.

With the latest commitments, Scout and Rivals rank Penn State's 2017 recruiting class as 14th in the nation and fourth in the Big Ten. The Lions receive a No. 15 ranking from 247Sports, and third in the Big Ten. All three services list the Lions with nine four-star recruits and eight three-star players.

National signing day is Feb. 1.
