The Utah Jazz confirmed Thursday that they will match the offer sheet Paul Millsap signed with the Portland Trail Blazers.

A formal announcement is expected Friday.

Millsap, 24, signed last Friday with Portland for $32 million US over four years, with $10.3 million US up front.

Because he was a restricted free agent, Utah had the right to match the offer to retain him.

Millsap filled in nicely for injured starter Carlos Boozer last season, averaging 13.5 points, 8.6 rebounds and 30.1 minutes in 76 games (38 starts).

He also had a string of 19 straight double-doubles.

Boozer, who missed 41 games with a knee injury, will likely be traded to lower Utah's player payroll, which stands at more than $80 million US with Millsap's salary.

Millsap is a 52.3 per cent shooter as a pro, having averaged 9.4 points, 6.4 rebounds, 1.2 assists and 22.8 minutes in 240 NBA games (41 starts) since he was drafted in the second round (47th overall) by the Jazz in 2006.
