The University of Southern California announced plans for extensive renovations for the Los Angeles Memorial Coliseum that could allow it to stage the 2024 Olympics and also serve as a temporary site for an NFL team next season.

The $270 million renovation will bring premium suites and boxes, along with more aisles and new seating for the entire stadium.

"Everybody is going to get a new, great fan experience," USC athletic director Pat Haden told reporters. "You don't have to climb over 18 people to get a hot dog."

Construction is not expected to begin until after the 2017 USC football season and could be completed by the start of the 2019 season.

Todd Dickey, USC's senior vice president, said the NFL has "strongly indicated" the league would like a team to play at the Coliseum in 2016, possibly for two or three seasons.

The NFL has blamed an error by a clock operator, and the failure to correct it by on-field officials, for an unusual run-off of 18 seconds near the end of the Pittsburgh Steelers' 24-20 victory Monday night over the San Diego Chargers.

The performance of those responsible will be reviewed as per standard procedure, according to league spokesman Michael Signora.

The incident occurred after a touchback as the Steelers gained possession for their game-winning drive late in the fourth quarter. By NFL rule, the clock should not have started because the receiving team possessed the ball in the end zone without taking it onto the field of play.

The clock continued to run, however, and when the Steelers huddled, the clock showed 2:38 remaining instead of 2:56, as it should have.

Official game time is kept on the stadium scoreboard, which is operated by a league-hired local resident who usually has college football officiating experience.

Some owners believe the St. Louis Rams and San Diego Chargers may be able to strike a deal to work together on a football stadium in Los Angeles.

The Rams have previously wanted to work alone on their proposed stadium in Inglewood, while the Chargers have been working with the Oakland Raiders on a site in Carson.

Some owners actively oppose Stan Kroenke’s desire to move the Rams, believing that Dean Spanos has tried long enough to get a new stadium in San Diego.

The Raiders have become an afterthought with the Rams-Chargers impasse.

Donald Brown has been released by the San Diego Chargers to make room for Michael Ola.

Brown signed a three-year, $10.5 million contract with $4 million guaranteed in 2014.
