Joe Flacco's targets are dwindling fast at tight end and wide receiver

OWINGS MILLS, Md. -- The Baltimore Ravens are not saying whether quarterback Joe Flacco will play Thursday's preseason game. The bigger question is who he would throw the ball to if he did suit up.

By the end of Monday's practice, the Ravens were left with just one tight end (Benjamin Watson) who wasn't injured or facing suspension, and nearly half of their wide receivers are sidelined.

The Ravens' tight end group was hit hard again Monday, when Maxx Williams and Daniel Brown both left practice early. Williams suffered a noncontact injury, and Brown took a vicious shot to the chin from cornerback Sam Brown.

Coach John Harbaugh initially indicated Williams' injury wasn't serious.

"I don't really know, to be honest with you," Harbaugh said. "I'm here at the press conference, and I haven't talked to the trainer yet."

Crockett Gillmore injured his hamstring on July 29 and hasn't returned. Dennis Pitta has been out since spraining his finger on Monday. With Williams and Brown hurt, the Ravens were down to Watson, Darren Waller and Nick Boyle in Monday's practice.

But neither Waller nor Boyle will be available at the start of the regular season. Waller is suspended for four games for violating the league's substance-abuse policy, and Boyle will be out 10 games for his second violation of the NFL's policy on performance-enhancing drugs.

The Ravens aren't faring much better at the wide receiver position. Of the team's 12 receivers, there are five dealing with injuries: Steve Smith Sr. (Achilles), Breshad Perriman (knee), Michael Campanaro (undisclosed), Chris Moore (lower left leg) and Chris Matthews (undisclosed).
