Pacers Sports & Entertainment says it plans to announce "major improvements and upgrades" to Bankers Life Fieldhouse on Thursday at a 2 p.m. press conference.
The 13-year-old arena hosts the home games of the Indiana Pacers and Indiana Fever professional basketball teams.
A source with knowledge of the planned changes said those improvements will include a new scoreboard and a renovation of the arena's television studios.
Pacers spokesman Greg Schenkel declined to comment on the nature of the improvements.
Nearly two years ago, the Pacers spent $1.6 million to install "ribbon boards" that display advertisements and other information around the perimeter of the 18,000-seat arena. That project was paid for with money from the Capital Improvement Board, the city agency that owns the Fieldhouse and leases it to the Pacers for $1 a year.
In 2010, the CIB agreed to pay $3.5 million for upgrades to the Fieldhouse because the Pacers said they were losing money each year on operating costs for the facility. The CIB also gave the Pacers $30 million in subsidies over the past three years. City and Pacers officials are now in discussions about a new deal.
