The Seattle Seahawks have officially signed quarterback Geno Smith. Pro Football Talk's Josh Alper wrote about the development on Wednesday.

The Seahawks left themselves with two quarterbacks and an empty roster spot after making some transactions earlier this week and that suggested a report they'd sign Geno Smith was on the mark.

Smith officially became a member of that the team on Wednesday when the Seahawks announced that he has agreed to a contract.

Seahawks.com reporter John Boyle also confirmed Smith's signing on Wednesday. Seattle now has three quarterbacks on its roster: Russell Wilson, Paxton Lynch, and Smith.

With Wilson as the starting quarterback, Smith will compete with Lynch for the backup role in training camp. Many expected the Seahawks to fortify their quarterback lineup, per ESPN.

Prior to Smith's signing, Lynch was the only veteran backup signal caller Seattle had. The Seahawks waived undrafted rookie quarterback Taryn Christion on Monday.

According to the ESPN report, Seahawks head coach Pete Carroll “appeared underwhelmed by how Christion and tryout players Troy Williams and Michael O'Connor fared at the team's rookie minicamp.”

Prior to signing with the Seahawks, Smith suited up in five games for the Los Angeles Chargers last season. Seattle already expressed interest in Smith before he signed with L.A., per ESPN.

Smith should make the backup quarterback competition in Seattle interesting. It'll be interesting to see him on the sidelines as Russell Wilson's backup. However, he has to beat Lynch first.

The New York Jets made Smith the 39th overall pick of the 2013 NFL Draft out of West Virginia University.

In 40 career games with the New York Jets, New York Giants, and Los Angeles Chargers, Smith has thrown for 6,182 yards, 29 touchdowns, and 36 interceptions.
