The Seahawks were fielding trade offers for Rubin in the days leading up to the roster cut deadline and the Broncos came up as a potential option, but no deal ever surfaced and he was cut loose a few days ago.
This is the first reported interest in Rubin since he became available.
Rubin, 31, is a former sixth-round pick of the Browns back in 2008. He spent seven years in Cleveland before signing a one-year deal with the Seahawks.
Rubin was entering the second year of a three-year, $12 million contract that contained $5.5 million guaranteed and set to earn a base salary of $1.7 million this year when the Seahawks cut him loose last weekend.
