Can Tyler Eifert have a repeat game for Bengals?

The Cincinnati Bengals (1-0) open their home regular-season schedule at 1 p.m. ET Sunday vs. the San Diego Chargers (1-0). Here are a couple things to watch for during the game:

Why watch: One reason you will want your eyes glued to the television screen is to see whether Bengals tight end Tyler Eifert can repeat his exploits from last Sunday at Oakland. In the opener against the Raiders, he had nine catches for 104 yards and two touchdowns. It was Eifert's first game action since dislocating his right elbow just eight plays into the 2014 season opener. Much like they attempted to use him last season, the Bengals last Sunday regularly placed Eifert in the seams, throwing him passes that could be caught in single coverage against a smaller safety or slower-footed linebacker. That's the matchup nightmare he could pose all this season if he can stay healthy. Likely to see veteran Chargers safety Eric Weddle often, Eifert will have to do what he can early to exert his dominance over San Diego's secondary. If for whatever reason he struggles to do that, the Bengals feel good about their other passing options. Receivers A.J. Green, Marvin Jones and Mohamed Sanu could benefit from any extra attention Eifert receives. So, too, could running back Giovani Bernard, who was dangerous in Cincinnati's short-passing game last week.

Keep your eyes peeled ... For how well the Bengals' defensive linemen counter the slightly sidearm-throwing Philip Rivers. Although he's 6-foot-5, San Diego's quarterback has a knack for throwing from a lower arm slot than most quarterbacks, almost pushing the ball out of his hand with the back of his body. It obviously hasn't caused Rivers many problems over the years, as his five-time Pro Bowl status indicates. Still, this could be a good game for the Bengals' tall pass-rushers to get their hands up to tighten some of the passing lanes Rivers will have. At 6-foot-6 and 6-foot-7 respectively, Bengals defensive ends Carlos Dunlap and Michael Johnson have considerable length coming off the edge. So do backups Will Clarke and Margus Hunt, who are 6-foot-6 and 6-foot-8, themselves.

Did you know? The very first game in Bengals' history was played against the Chargers. OK, maybe you're a die-hard Bengals historian and you did know that. But did you know what night of the week it was when the game was played? It was a Friday. The Sept. 6, 1968 game in Southern California was won by the Chargers, 29-13.
