The running back from Tennessee was injured on a 1-yard run on the Ravens' third offensive play, his first live tackle play as a pro against another team. Lewis was carrying the ball in his right arm and was trying to use his left to keep his momentum going when a defender rolled over it.
"I thought it was broke," Lewis said. "I'd never felt that kind of pain before. Luckily, it was just dislocated."
Lewis walked to the sidelines, where trainers popped the elbow back into place.
Coach Brian Billick said Lewis was having a great training camp and should be back in time for the Sept. 3 regular season opener at Pittsburgh.
"He was picking up the system and catching the ball well," Billick said. "His speed jumps out at you."
But the time missed will be crucial for a rookie expected to work his way into the starting lineup.
"I keep saying, if we didn't need to do this, we wouldn't," Billick said. "We'd get up in the morning, have a meeting or two, go play golf and come back and show up for the opener. You need that for timing, you need to get a feel for the system."
The scrimmage was cut short when a thunderstorm hit with the Ravens leading 3-0. Players were ordered off the field and the estimated 20,000 fans were told to seek safety in the enclosed concourses. Officials hoped to resume play, but the storm lingered and the coaches decided it would be unsafe to continue.
Each team's offense had completed one set of plays under the controlled scrimmage rules, and the Redskins had just begun their second set, when the rain began. The scrimmage featured reserves almost exclusively, although the starters for both teams took part in 7-on-7 drills beforehand.
The Redskins started three drives at their own 35-yard line during their set of plays, and Chad Dukes' 23-yard run was the only big gain. The final drive ended with an interception by Ravens veteran safety Corey Harris.
The Ravens also got the better of the Redskins in the 7-on-7s. Tony Banks threw back-to-back 20-yard touchdown passes to wide open receivers, the first to Jermaine Lewis racing past Champ Bailey and the second to Shannon Sharpe with Sam Shade trailing.
At the other end of the field, the Redskins skill players sputtered, with Brad Johnson throwing mostly short passes that fell incomplete or for little gain. Backup Jeff George had the best throw of the night, hitting Irving Fryar on a 20-yard sideline pattern for a touchdown.
Sanders, nursing back spasms, practiced at Redskins Park earlier. Sanders' one noticeable duty was bringing the water cart onto the field during one drill.
Absent for the Ravens was holdout draft pick Travis Taylor, although his jersey number was evident on a fan's banner that read: "C'mon 89, play fair."
The Redskins said they sold 45,000 tickets for the scrimmage and the concert that followed, but the crowd appeared to be less than half that number. Still, the scrimmage had some of the facets of a real game, including a national anthem and frequent TV timeouts.
