Caldwell said tight end Ed Dickson, who has been practicing for about a week now after tearing his hamstring earlier in training camp, looks as explosive as he did before he was injured. "He's running well, he's catching the ball well. That's coming along well," Caldwell said. … Acquired last Wednesday, running back Delone Carter is expected to get some playing Thursday, though how much he plays will likely depend on how quickly he learns the offense. … Orioles right fielder Nick Markakis and his family watched the Ravens' practice Monday. … A group of nuns also visited practice and shook hands with coaches and players afterward, prompting Pees to say, "All the help we can get. We'll use everybody."
