LOS ANGELES -- The University of Southern California has plans for a $270 million upgrade for the home field of the Trojans -- the Los Angeles Memorial Coliseum -- that could become a stage for the 2024 Olympic Games and a temporary site for an NFL team.

The renovations would include the construction of premium suites, more aisles and new seating. Renderings are available here.

The plans outlined Thursday are preliminary.

And a question mark is money. USC needs to raise it through gifts, sponsorships and donor naming rights.

Construction is not expected to begin until after the 2017 USC football season.

The NFL is considering moving into the L.A. market after a two-decade absence.

USC executive Todd Dickey says the NFL has "strongly indicated" the league would like a team to play there in 2016.
