Three things to watch as the Carolina Panthers play the Baltimore Ravens on Thursday at 8 p.m. ET in a game that will be broadcast on ESPN:

Cam Newton and Jimmy Clausen. Newton will get his most extensive playing time of the preseason, and the Panthers hope he and the offense can get in a rhythm. Newton has led only one touchdown drive this preseason. Clausen is expected to play with the second team. That’s not a sign that Clausen has a chance to beat out Derek Anderson for the backup job. It’s more of a sign that the Panthers want to take a good look at Clausen before deciding if they want to carry two or three quarterbacks on the roster.

The receivers. Armanti Edwards, Domenik Hixon and Joe Adams aren’t expected to play due to injuries. That means more playing time for Ted Ginn Jr. and David Gettis, who are having strong preseasons and have a chance to be among the top backups at receiver.

Garry Williams. He’s been getting the first-team work at right guard since the team released veteran Geoff Hangartner. Williams needs a strong showing because it still is possible the team could bring in a veteran as other teams trim their rosters.
